Busking setup and other Stuff.

Here is my current busking setup. 

AMP: Line 6 MicroSpider. Portabel busking amp with 6 C size batteries $300 The MicroSpider comes with built in guitar effects including a channel for acoustic guitar. also mic input and a mp3 player input.

Power Supply: PowerPac PP12-7.5 12Volt, 7.5Amp Hours  (better than Csize batteries) $30-$50 
Vansen SDR-1500 Regulated Power Adaptor $20

Miceophone: cheep $30 one from www.trademe.co.nz. (needs upgrading) and mic stand. 

Instrument: Seagul acoustic guitar or Greg Bennit Sammic Baratone Ukulele, Harmonica with playing stand  Other Gear: Mic stand, folding Music stand, Portable trolley click here $100 small folding chair. any will do. as long as it is is a good hight of the ground to sit and play similar to click here. small Plastic box with lid to store gear. similar to click here. also i attached a 2 pipes to the back of the trolly with a cover on the bottom to cary the mic and music stands.  

 appart from the instruments a similar setup would cost around $500-$600 dollars to setup. 
it depends on what you are doing. as to what exact gear you end up getting.

I have also seen people using the Rolland street cube amp which is a nice cheep amp for busking

also rolland have now got a new busking amp for acoustic guitarists called the ac-33. this is a great amp and one day i am going to upgrade my MicroSpider with this. the nice thing is that the amp has a built in overdubbing looper. Phill Keaggy does a nice demo of the amp here

Aer make a really nice portable battery amp but they are up there in price.

Here is the Aer live on Queen St Auckland played by Luke Hurley

here is just my experience and ideas on the subject of busking gear and setup.
